摘要：

Mössbauer experiments on Dy161 in DyCrO3 are reported. At 4.2A°K the paramagnetic hyperfine pattern was found to be consistent with the following interactions for the ground state of Dy161: g0βNHeff=-806±20 Mc/sec and 14e2qQ=420±20 Mc/sec. The dysprosium spin relaxation times are τ(20A°K)≤7×10-9 sec and τ(78A°K)a. 5×10-11 sec. The crystal-field constant V20 was estimated to be 159 cm-1. © 1969 The American Physical Society.
